MEANS FOR PROTECTING COKE-OVENS.

SPECIFICATION forming part of Letters Patent No. 725,749, dated April21, 1903.

Application filed September 10, 1902. Serial No. 122,752. (No model.)

To aZZ whom, it may concern:

Be it known that I, EDWIN A. MOORE, acitizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in Meansfor Protecting Coke-Ovens; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates, primarily, to cokeovens of the type known as theOtto-Hoffman, has for its object the protection of the brickwork againstdeterioration from exposure to the elements and prevention of radiationof heat through the top of the oven, and consists in certainimprovements in construction, which will be fully disclosed in thefollowing specification and claims.

In the accompanying drawings, which-form part of this specification,Figure 1 represents a vertical transverse section of a coke-ovenprovided with my improvements; Fig. 2, a front elevation of a section ofa battery of coke-ovens; Fig. 3, a vertical transverse section on anenlarged. scale; Fig. 4, a horizontal section on line 4 4, Fig. 1; andFig. 5, a vertical section on line 5 5, Fig. 1, showing theairchamber-inclosing the transverse tie-rods.

Reference being had to the drawings and the designating charactersthereon, 1 indicates the supporting columns, 2 the gasfiues, 3 thetroughs supporting said fines, 4 the floor, and 5the tie-rods, all ofwhich are shown, described, and claimed in my ap-' plication, Serial No.122,751, filed September 10, 1902.

It is well known that the masonry of cokeovens exposed to the elementssuifers great deterioration, resulting in washing out the mortar betweenthe courses of brick, in the cracks formed in the masonry by expansion,and the breaking off of the brick on the edge of the top of thestructure, and that the heat radiated through the top of the structureis so great as to seriouslyinterfere with the comfort of the men who arerequired to work there. This radiation of heat also becomes a matter ofloss in the operation of the ovens, and therefore enters into the costof producing coke.

It is my purpose to incase the sides of the structure,-in which are theopenings to the ovens, with metallic sections or panels provided with amaterial to prevent the radiation of heat through the panels and toprotect the top of the structure against radiation of heat and wear andtear of the elements.

The metallic sections or panels are indicated by the numeral 6 below theoven-openings 5, and 7 above the same, and are each provided with arecess 8 in the rear side thereof, which recess is filled with asbestos,mineral wool, or other suitable material 9 to prevent radiation of heat.The sections or panels 6 and 7 are secured in position by hollow castiron pilasters 10, which rest upon the panels at their adjacent edges,and upon the pilasters rest buckstays 11,which extend throughout theheight of the structure and are secured in position by rods 12,extending across the structure,with a nut on the rod. At the lower endof the panels transverse bars 14, of angle-iron, are applied to hold thebuckstays .to the panels, and these bars are secured in position by rods15, also extending across the structure. The transverse rods or bolts 12are incased in a chamber 16, formed by two sections 17 18 ofchannel-iron to protect. the

rods from intense heat by the circulation of l air through the chambersaround the rods or overlapping the panels 7 at their upper end,

andhaving a lip 20, which engages the panels, and the edges of thepanels 19 overlap each other, as shown at 21 in Fig. 2.

Under the panels are asbestos fillings 22 in sheets or in blocks, and atthe inner end of the panels are raised portions 23, which span or crossa channel 24 to allow for expansion of the masonry and rest upon theconcrete surface 25 to move freely thereonas the masonry expands andcontracts.

26 indicates two courses of. hollow tiles forming dead-air chambers toprevent radiation of heat'from the ovens, and above the upper course oftiles and dead-air chambers is placed asbestos felt 27, in two or morelayers, then two'or more layers of tarred paper 28, upon which is laidcement 29, then a layer or sheet of expanded metal 30, which in turn iscovered with cement 31, thus forming a covering which prevents radiationof heat from the ovens and thoroughly protects the top of the structureagainst the destructive effects of the elements and presents a durablewearing-surface. The tiles of the lower course, resting on the floor t,are closed at their ends to form dead-air chambers in the tiles toprevent radiation of heat from the ovens.

Having thus fully described my invention, what I claim is 1. Acoke-ovenhaving its sides incased in metallic sections provided with recesses inthe rear sides thereof, and heat-non conducting material in saidrecesses.

2. A coke-oven having metallic sections provided with recesses in therear sides thereof filled with a heat-non-conducting material, coveringthe sides of the oven and the top edges thereof, the latter sectionsengaging the upper edges of the sections on the sides of the oven, andmeans for securing the sections to the masonry.

3. A coke-oven having its sides incased in metallic sections providedwith a heat-nonconducting lining; in combination with the buckstaysofthe oven, engaging and retaining said sections in position.

4. A coke-oven having its sides incased in metallic sections; incombination with pilaste'rs engaging said sections, buckstays en-
